FOM-5A, FOM-6A
CMN-CF8 – sync/async fiber optic modem
card with V.54 loops, compatible with
FOM-8
CMN-C11 – async short range modem card
with V.54 loops, compatible with ASM-11,
and with ASM-10/8 and SRM-8 in async
mode
CMN-CEB – elastic buffer for connecting
two independently clocked DCEs
CMN-C423/422 – interface converter from
RS-423/V.10 to RS-422/V.11
Several plug-in power supplies are available
for 115/230 VAC and –48 VDC operation.
The card nest can be supplied with two
totally independent plug-in power supply
units, providing redundancy and automatic
backup. A standalone 115/230 VAC high
power version supports two card nests via
cable and card connection.
The CMN-16 is available as a 19" rack
mount enclosure and is 2U (3.5") high.

The CMN-16 compact modem nest is a space-saving
rack that houses up to 16 short range modem cards.
Most of the cards carry two modems, doubling the
capacity of the nest to up to 32 modems. The nest
provides an inexpensive solution to central site racking
of short range modems. In addition to short range
modems, the nest supports interface converters, fiber
optic modems and elastic buffers.
The CMN-16 is compatible with the SRM short range
modem family and has the added capability of
displaying activity on the interface signals.
